My inventionrelatesmore particularly to Patented Nov. 25; 1930 Visesotthe type ,com'prisinga base presenting a portion against whlchtheartlcle, as

One of .my objects is to; provide anovel,

simple,'strong, andi'economical construction of vise; another object istoprovide as a part separable from the. base, a jaw member against whichthe article is clamped which shall present a relatively long bearingsurface for the article, a portion of which bearing surface directlyopposes the flexible element therebyavoidingbuckling of the article,especially in thevcaseof ;a pipe ;-to:pro-v *vide such a jaw memberwhich shall be inexpensivetofi construction,

The preferred-illustrated embodiment of my invention comprises a base5iat which the device is adapted to be secured to a support, as forexample to the top, of a table, as by bolts passing through openings 6in the base.

The base 5 is formed of a ribbed attaching a plate section 7 in whichthe bolt-receiving openings'6 are l0cated,andat one end ofthe section"(with parallel 'verticali ;relatively" 1 i The upper edge portionsofthetplates 8 andmay be readily assembled with,'ancl removed from,thebase of the vise another object is to provide a con- [struction ofconnection between the free end COIRPQRATION' or ninmors Apgilicatizjnfiled lebruar y 4,1929.

otally connected byapin apart ears 22, between which the chain ex tendsand de ending 'fromftheouter ender fltc 21 "with spaced a lever 23located between the plates 8 and fulcrumed thereon as represented at 24,the lever 23 cooperating with a threaded actuating rod 25 engaging atits threads with the threaded opening 26 of a sleevelike boss 27 shownas integrally formed with the plate portions 8. The rod 25 is positionedto bear against the outer, free, end of the lever 23 for exerting atightening action on the chain 20, the outer end of the rod 25 beingshown as provided with a handle 28 for operating it.

The opposite end of the chain 20 is adjusts ably connected with the base5 to adapt the device for the clamping of articles of widely differentdiameters. The chain shown comprises a series of links 29 adjacent onesof which are connected together by pins 30 extending outwardly beyondthe links 29 as shown and in accordance with common practice. The end ofthe chain provided for adjustable connection with the base 5 as statedextends into the space between the plates 8 which latter are provided ontheir inner surfaces with portions 31 integral therewith and each shapedto present an upper pair of recesses 32 and 32 and a lower pair ofrecesses 33 and 33.

The recesses 32 and 33 are disposed in planes below the recesses 32 and33, respectively, and the recesses 32 and and 32 and 33 are spaced apartvertically a distance corresponding with the spacing of adjacent pins 30and with which the ends of adjacent ones of these pins may beselectivelyinterlocked in the adjustment of this end of the chain, as for examplewith the recesses 32 and 33 as shown by Fig. 3. The feature of providingupper and lower recesses spaced apart as stated is of advantage as thechain is there by anchored verysecurely to the base and danger ofbreakage of the parts is minimized; and the feature of providing therecesses 32 and 33 below the recesses 32 and 33, respectively, is ofadvantage as it provides for closer adjustment of the chain.

The feature of providing the jaw member 12 and positioning the chainrelative thereto as shown, is of advantage as a firm grip may beobtained on articles of widely different diameters and with the minimumdanger of crushing or otherwise distorting the articles.

While I have illustrated and described a particular constructionembodying my invention, I do not wish to be understood as intending tolimit it thereto as the same may be variously modified and alteredwithout departing from the spirit thereof.

What I claim as new, and desire to secure by Letters Patent,is:

l. A vise comprising an attaching plate provided with an upstandingwall, an upstanding wall parallel to and substantially coextensive withthe first mentioned wall, webmeans connecting said walls, said wallsabove the web means having cutaway portions, a jaw disposed over the webmeans and in said cutaway portions, a fastening means between the webmeans and jaw, a fulcrum member connecting said walls, a lever movablebetween the walls and pivoted on said fulcrum member, a flexibleclamping element connected to the lever, means whereby the flexibleelement may be secured in anchored relation to said walls, and anadjusting means mounted by one of said walls and operable against saidlever.

2. A vise comprising an attaching plate having an upstanding wall at oneedge thereof, said wall being elongated and projecting at one sidebeyond the plate, an upstanding wall parallel to and substantiallycoextensive with said first-mentioned wall, a hollow web means integralwith said walls, said walls above said web means having cutawayportions, a jaw disposed over the Web means and engaging said cutawayportions, a fastening extending through the web means and engaging thejaw to hold the same in place, a fulcrum member connecting said wallsand disposed remote to the plate, a lever operable between said wallsand pivoted on said fulcrum member, a flexible clamping element securedto the lever, means whereby said clamping element may be anchoredrelatively to said walls, said jaw at opposite sides thereof beingcutaway to accommodate the flexible element when engaged with relativelysmall work, and adjusting means mounted on one of said walls andoperable against said lever.
